ApolloHelix API

Endpoint reference for programmatic access. Every request requires an API key.

The ApolloHelix API is protected with enterprise-grade security standards (API-key authentication, rate limiting and encrypted connections). Authorization is required for access.

Authentication

Send your API key in the x-api-key header on every request. Keys are created in Dashboard > Developer Settings.

header

x-api-key: YOUR_API_KEY

A key is shown only once, when it is created; only its hash is stored on the server. Keep your key secret.

Rate limits

Requests are limited per key, per minute. When the limit is exceeded the API returns 429 and you can retry after a minute.
